class_docstr: Generates two-dimensional grid graphs.
  See :meth:`~torch_geometric.utils.grid` for more information.
  
  Args:
      height (int): The height of the grid.
      width (int): The width of the grid.
      dtype (:obj:`torch.dtype`, optional): The desired data type of the
          returned position tensor. (default: :obj:`None`)

      return (
          f"{self.__class__.__name__}(height={self.height}, "
          f"width={self.width})"
